我有一个gridview gdvNotification。第一次加载页面时：我的gridview有分页。
我的问题是：
javascript:__doPostBack('ctl00$MainContent$gdvNotification','Page$2')，它正常工作。调用了gdvNotification_PageIndexChanging事件。以下是我的观点：
<asp:GridView ID="gdvNotification" runat="server" AutoGenerateColumns="False" Style="width: 100%;"
BorderWidth="0px" CellSpacing="0" CellPadding="0" GridLines="None" PageSize="1"
AllowPaging="True" ShowHeader="false" OnPageIndexChanging="gdvNotification_PageIndexChanging">
<HeaderStyle CssClass="BasicColumnTitle" />
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Panel ID="panel1" runat="server" Width="100%" Height="618" ScrollBars="Vertical">
<table style="width: 100%;">
<tbody>
<tr style="height: 40px">
<td class="BasicValue" style="vertical-align: bottom;padding-left:2em">
<div>
<asp:Label ID="lblhead" CssClass="bold" runat="server" Text='<% #Eval("Subject")%>' Style=" font-weight: bold"></asp:Label>
</div>
</td>
</tr>
<tr style="height: 40px">
<td class=" BasicValue" style="vertical-align: bottom ;padding-left: 2em;">
<div>
<asp:Label ID="Label2" runat="server" Style=" font-weight: bold" Text='<% #Eval("AuthorName")%>'></asp:Label><asp:Label
ID="Label3" runat="server" Style="float: right" Text='<%# string.Format("{0:yyyy/MM/dd hh:mm}",Eval("BulletinDateFrom"))%>'></asp:Label></div>
</td>
</tr>
<tr style="height: 40px">
<td class="BasicValue" style="vertical-align: bottom">
<div>
<asp:Label ID="lblSection" runat="server" Style="padding-left: 2em;" Text='<%# GetSectionName(Eval("Id").ToString())%>'></asp:Label>
</div>
</tr>
<tr style="height: 497px;">
<td class="BasicValue" style="text-align: left; vertical-align: top; padding-left:2em ">
<asp:Label ID="lblContent" runat="server"
Text='<% #Eval("Contents")%>'></asp:Label>
</td>
</tr>
</tbody>
</table>
</asp:Panel>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
页面加载方法：
protected void Page_Load(object sender, EventArgs e)
{
logger.Debug("Handle event page load.");
if (!IsPostBack)
{
try
{
MasterDataHelper.RefreshCacheHeadLine();
//Get time display from system parameter
logger.Debug("Get limit new data display list.");
IList<SystemParamEntity> limitNewDataDisplayList = MasterDataHelper.GetSystemParamEntityByKbn(limitDataKBN);
IList<decimal> limitNewDataDisplayList1 =
(from item in limitNewDataDisplayList where item.DelFlg == false select item.Param1).ToList();
if (!limitNewDataDisplayList1.Any())
{
string msg = string.Format(Messages.I00010, "新規表示期間");
logger.Error(msg);
}
else
{
limitNewDataDisplay = limitNewDataDisplayList1[0];
this.hdflimitNewDataDisplay.Value = limitNewDataDisplay.ToString();
}
//Get data from session and cache
GetDataFromSessionAndCache();
//TODO: check business input datetime.now
var searchresult = ProcessFuzzySearch(DateTime.Now, SessionUtil.GetFromSession<string>(SESSION_FUZZYSEARCH));
txtFuzzySearch.Text = SessionUtil.GetFromSession<string>(SESSION_FUZZYSEARCH);
lblDate.Text = string.Format("{0}年{1}月{2}日（{3})", DateTime.Today.Year, DateTime.Today.Month, DateTime.Today.Day,
GetDayOfWeek((int)DateTime.Now.DayOfWeek));
pnPageIndex.Visible = false;
grvHeadline.DataSource = searchresult;
grvHeadline.DataBind();
if (searchresult.Count > 0)
{
string notificationIdSelected = searchresult[0].Id;
hdfNotificationIdSelected.Value = searchresult[0].Id;
HeadlineSelected(notificationIdSelected, 0);
grvHeadline.SelectRow(0);
}
else
{
//if: notification.count=0 => disable button edit notification
btnEditNotification.Enabled = false;
ClearDataAndDisplayForGridNotification();
}
}
catch (ApplicationException ex)
{
logger.Error(ex);
}
//Check permission for button add new head line and update notification
checkPermission();
}
}
}
为gridview grvNotification方法绑定数据：
private void HeadlineSelected(string notificationIdSelected, int index)
{
logger.Debug("Head line selected");
GetDataFromSessionAndCache();
IList<InformationEntity> infoNotificationList = new List<InformationEntity>();
if (string.IsNullOrEmpty(notificationIdSelected))
{
//Clear
ClearDataAndDisplayForGridNotification();
btnEditNotification.Enabled = false;
}
else
{
infoNotificationList = MasterDataHelper.GetInformationByHighOrderId(notificationIdSelected);
logger.Debug("Notification list not null");
if (infoNotificationList != null)
{
if (infoNotificationList.Count == 0)
{
pnPageIndex.Visible = false;
hdfNotificationId.Value = string.Empty;
btnEditNotification.Enabled = false;
}
else
{
if (infoNotificationList.Count == 1)
{
fakepanel.Visible = true;
}
else
{
fakepanel.Visible = false;
}
if (base.IsPermission(PERMISSION_INFORMATION_FOLLOWUP))
{
btnEditNotification.Enabled = true;
}
pnPageIndex.Visible = true;
gdvNotification.PageIndex = index;
hdfNotificationId.Value = infoNotificationList[index].Id;
gdvNotification.DataSource = infoNotificationList;
gdvNotification.DataBind();
}
logger.Debug("Set value for label total page");
lblTotalPage.Text = gdvNotification.PageCount.ToString(CultureInfo.InvariantCulture);
lbPageIndex.Text = gdvNotification.PageCount == 0
? gdvNotification.PageCount.ToString(CultureInfo.InvariantCulture)
: (gdvNotification.PageIndex + 1).ToString(CultureInfo.InvariantCulture);
lbTotal.Text = infoNotificationList.Count().ToString(CultureInfo.InvariantCulture);
}
}
}
事件pageindex更改gridview gdvNotification：
protected void gdvNotification_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
logger.Debug("Gridview Headline page index changing .");
//gdvNotification.PageIndex = e.NewPageIndex;
HeadlineSelected(hdfNotificationIdSelected.Value, e.NewPageIndex);
//gdvNotification.DataBind();
lbPageIndex.Text = (e.NewPageIndex + 1).ToString(CultureInfo.InvariantCulture);
}
发生了什么事？
答案 0 :(得分：0)
“调用codebehide但不调用gdvNotification_PageIndexChanging事件。”
如果您正在收到回发但该函数未被调用，则Page_Load方法中的某些内容可能会阻止事件发生。你不是在重新填充GridView吗？你忘了吗
if (!Page.IsPostBack)
